Sony tests anti-CD burning technology

As part of its mounting United States rollout of content-enhanced and copy-protected CDs, Sony BMG is testing technology that bars consumers from making additional copies of burned CD-R discs.

Since March the company has released at least 10 commercial titles - more than 1 million discs in total, featuring technology from UK anti-piracy specialist First4Internet that allows consumers to make limited copies of protected discs, but blocks users from making copies of the copies.

The concept is known as "sterile burning" and, in the eyes of Sony BMG executives, the initiative is central to the industry's efforts to curb casual CD burning.

"The casual piracy, the school-yard piracy, is a huge issue for us," Thomas Hesse said, president of global digital business for Sony BMG.

"Two-thirds of all piracy comes from ripping and burning CDs, which is why making the CD a secure format is of the utmost importance."

Names of specific titles carrying the technology were not disclosed.

The effort is not specific to First4Internet.

Other Sony BMG partners are expected to begin commercial trials of sterile burning within the next month.

To date, most copy protection and other digital rights management-based solutions that allow for burning have not included secure burning.

Early copy-protected discs as well as all Digital Rights Management (DRM)-protected files sold through online retailers like iTunes, Napster and others offer burning of tracks into unprotected WAV files.

Those burned CDs can then be ripped back onto a personal computer minus a DRM wrapper and converted into MP3 files.

Under the new solution, tracks ripped and burned from a copy-protected disc are copied to a blank CD in Microsoft's Windows Media Audio format.

No matter`

what they do to try to protect the content, you can stil capture it from the audio stream as it is played (as a .wav), then that file can be converted to an unprotected format. If the person is intent on "stealing" the data, there is not much they can truly do to protect it.

??????????

Where did you find this article? I dont like the idea of limited copying but I do understand so I cant really complain. My question is how does the original reduce the copy vs. the copies making it less? IS that encoded into the cds or is it only on newer buring software that make it possible? If so people will just use older software until the new originals wont be compatible with the older software. Lately I've noticed a steep decrease in burner prices, coincidence?

Not sure I completely understand your question but basically some CD and DVD originals contain can contain more data than the CD or DVD you purchase ie DVD may contain 7GB where the one you purchase can only fit 4.7GB.

You need "shrinking software" to compress and also "decode" the Copy Protection ( illegal of course )
